A 54-year-old woman developed epilepsy and gait disorder. The initial CCT showed multiple intracerebral cysts. Histologically these turned out to be cavities from repetitive bleedings out of abnormal vessels in the border region. Regular observation during 7 years showed spontaneous episodes of regression and progression of the cysts. In addition, multiple hemangiomas of the skin were found. The case presented here represents an unusual manifestation of neurocutaneous angiomatosis.
